Along with Omaha Police, the troopers held three surprise inspections -- one on Rainwood Road and North 111th Street, another at 60th and Harrison streets, and a third in Elkhorn near the intersection of Highway 64 and Highway 31.

The effort was a part of the Metropolitan Aggressive and Preventative Electives, or MAPS, Tuesday.

"We're trying to get more of the local trucks today that we don't get to as often and make sure they are still in compliance," Sgt. Phil Thede said. "And if not, we'll help get them into compliance."

A lot of the effort was educational, like cargo being improperly secured and the total weight of a truck needs to be within regulations.

"This guy went and rented this trailer and didn't know he was under federal regulations," Lt. Jon Beckstead said of one of the drivers.

The Nebraska Trucking Association supports the inspections, saying it has made roads safer.

"It's good to some extent," said driver Duwayne Schmelzer.

Schmelzer has been a commercial driver for 41 years. He said the extra enforcement had weeded a number of bad operators off the road.

"A lot of them went out the door," Schmelzer said. "Which is fine, we don't need that."

The troopers were also looking for suspicious cargo and terrorist activity.

"I don't think it's going to leave our minds, our generation's minds for years to come," Thede said. "So we are always diligent for what might be out there as far as national security issues."
